To a/ZZ whom, t may con/cern.'

Be it known thatv I, EDWARD ALFRED KLAGES, a citizen of the United States, and a resident of Grafton, in the county of Allegheny and State of Pennsylvania, have`invented new and useful Improvementsin Window-Fasteners, of which the following is full, clear, and exact description.

My invention relates to certain novel and useful improvements in sash-fasteners, and has particular application to fasteners ofthe character adapted to be employed in lockingA or securing windows of the type commonly known as sliding sashes.

One of the primary objects of my invention is the provision of al fastener which shall he composed of two main members, a locking member and a keeper therefor, such members being adapt-edV to be fastened on adjacent meeting-rails and securely hold the two said yrails in alinement, so that one of the sashes can be moved relatively to the other only when the locking member is detached or released from its keeper.

A further object is, to devise an improved sash-fastener which shall'be composed of relatively few parts and formed of cast or wrought metal, or both, thereby combining the essential features of efficiency, security, strength, and simplicity. I have also inrview the construction of a fastener which may be readily applied to sashes and shall not interfere with the raising and lowering of the same or with the curtains, shades, screens, or shutters of the window.

With these and other objects of a similar nature in view my invention consists in the pcculiar'construction, combination, and arrangement of parts, as will be hereinafter fully set forth. l

Although I have shown and hereinafter described one particular embodiment of my invention, I wish it to be understood that I do not limit myself to all of the` precise details of construction, as modifications and variations in some respects can be made without departing from the essential features of the invention or sacrificing any of the advantages thereof.

Reference is to he had to the accompanying drawings, forming a part of this specification,

in-which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a fragmentary perspective view y of two window-sashes of the type referred to and showing my improvement applied thereto. Fig. 2 is a vertical sectional view of the same, taken on the line 2 2 of Fig. 3. Fig. 3 isla vhorizontal sectional view taken on the line 3 3 of Fig. 2.' Fig. 4 is a longitudinal vertical sectional view of another form of my inventionin which the main parts are of wrought metal, and Fig. 5 is a transverse vertical sectional view taken on the line 5 5 of Fig. 4., f n

Referring now to the accompanying drawingsin detail and in particular to Fig. l thereof, A and B designate, respectively, upper and lower rails or bars of the window-sashes,

mal window-closing position, as shown, being adapted to aline and are held in such position of meeting or alinement by means of my fastener, which I shall now proceed to describe in detail.

To the upper sash A is secured the locking member of the fastener comprising a plate l, secured to thesash A by means of bolts or screws 2, passing through aperturesnear the ends of said-plate. Said plate has formed thereon the upwardlyextending approximately parallel lugs 3 3, adapted to receive the extension or reduced portieri l of the casing or housing 5, which casing contains the locking-bolt of the device. It will be observed that this casing or housing is pivotally supported by means of a pivot-rod 6, journaled in said lugs and passing through the reduced portion Ll. 'When free from its keeper member, the casing, whichhas linger-rests 7 7 formed thereon, and -its contained locking parts may be lifted by pressing upward and backward on the linger-key 20 and swung or moved on said pivot upward in the direction of the sash, but will be prevented from contacting with and breaking or damaging the glass in the window-frame by the edge of the said reduced portion abutting against the base-plate l. Y

As will be seen from an examination of the A drawings, the casing 5 of the locking member 'has its hollowed interior portion sufficiently ssvr ICO

large to accommodate the locking bolt or key 8, as clearly shown in Figs. 2 and 3. The key or bolt proper is formed of a fiat substantially rectangular metallic strip or block having a slot or an aperture 9 therein, for a purpose hereinafter described. This key or bolt is adapted to slide longitudinally in the housing andis retained and tensioned therein by means of a spring 10, which is fastened to the rear end of said bolt at one end and at its other extremity extends through the relatively narrow slotted portion 11 of the casing. When said locking-key is forced or pushed back in the casing, the rear end 12 of said key will be limited in its rearward movement by the rear wall 13 of the enlarged hollow portion of the casing, and a set-screw 14C, passing upward through the body 0f the bolt or key, has its end movable in the upper slotted portion 15 of the housing or casing, thereby guiding,l limiting, and supporting the aforesaid bolt in its longitudinal movement.

The keeper member which I employ in carrying out my invention consists, essentially, of a base-plate 16, adapted to be rigidly fastened to the meeting-rail of the lower sash by means of screws or bolts 16a. When the two meeting-rails are in the position shown in the drawings, the keeper-plate 16 is adapted to rest in approximately the same horizontal plane as the bolt, casing or member that is to say, substantially in alinement therewith. The keeper-plate is formed with an upwardlyextending stud or projection 17, provided with a recess or a transversely--directed groove 18, between the walls of which recess is adapted to be held the edge portion 19,forming the rear wall of the slot 9 in the key or bolt, the stud 17 passing through said slot iu the manner illustrated.

From the above description, taken in connection with the accompanying drawings, the Operation of my improved lock will be readily understood. The keeper member and bolt member having been secured to their respective rails, as heretofore described, when it is desired to securely lock the window the pivotal portion of the locking member is swung down from its vertical position to an approximately horizontal position upon the keeper member, the stud 17 of said keeper member passing through the slot in the bolt and the slot in the top portion of the housing or casing. The extension or tension spring will then force the key or bolt outwardly, and the edge 19 thereof will enter the recess 18 in the vertically-arranged stud 17, thus firmly securing the meetingrails against movement. When it is desired to unfasten the sashes, it is only necessary to push or press the front 2O of the locking-key inward, and the said key will be released from engagement with the stud, and the easing may then be moved or swung from its horizontal to its Vertical position and the sashes raised or lowered, as desired.

In Figs. 4 and 5 I have shown a slightlymodified form of lock, the keeper being formed substantially as in Figs. 1, 2, and 3, and the locking member has its back portion 19tl adapted to engage a recess 182L in the stud or projection 17?. The locking member is formed as an angle-iron-that is, with thelthere are many others which will suggest themselves. For instance, when the window is locked it is impossible to open the same with a sharp-pointed implement, such as a knife, or to insert a strip between the meeting-rails of the sash in such manner as to release the locking member. It will also be seen that in pulling down the pivoted casing to bring it into its engaging or locking position the curved faces of the projecting stud 17 or 17a will guide the sashes into lateral alinement, the back curve forcing the bolt rearward, while the inner curved portion will assist in drawing the sashes tightly together. The arrangement of the two finger-rests upon the casing permits one to use greater force when it is necessary to bring the sashes into alinement and lock them in such position. The device is composed of but relatively few parts and may be made entirely oi' metal, either wrought or cast, and presents but little liability of derangement when subjected to jars, shocks, or strains.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a window-sash fastener, the combination of a locking member comprising a base member, an apertured casing pivoted thereto, the upper rear edge of said casing being adapted to abut the base-plate and limiting the rearward movement of the casing, an apertured spring-tensioned block mounted to slidein said casing, and a keeper member having a single, centrally-arranged, upwardly IIO extending stud provided with a tranverse recess, said stud being adapted to extend through the apertures in the locking-block and in the casing, the construction being such that the block will form a locking en-
